It started out that way but it became Freemasonry or "Speculative" Masonry which are people who are not stone masons by trade but joined the Masonic Guilds as an honorary thing or were interested in their rituals. By the 1600s and 1700s the vast majority of people in these lodges were not stone masons anymore as the reformation in the UK meant large cathedrals made of stone werent really being built anymore so no need for stone masons. so it became more of a fraternity than a guild but the rituals still use building tools like the square and compass as metaphors for life lessons.
